Write a program which is required to process the time of a clock in hours and minutes, entered from the keyboard. With this program, there are two requirements for any data entered by a user: 1. The data must be of the correct type (in this case, two ints). 2. The data must be in the correct range: this means that, for the minutes, negative numbers and any number above 59 must be rejected; for the hours, negative numbers and any number above 23 must be rejected. Output error message for invalid data input. Output the time one and a half hour after the time input. i.e. Hour: 22 Min: 32 One and a half hour after 22:32 is 00:02
